Saudi Arabia has invested in Pakistani nuclear
weapons projects, and believes it could obtain atomic bombs at will, a
variety of sources have told BBC Newsnight.

While the kingdom's quest has often been set in the context
of countering Iran's atomic programme, it is now possible that the
Saudis might be able to deploy such devices more quickly than the
Islamic republic.

Earlier this year, a senior Nato decision maker told me that
he had seen intelligence reporting that nuclear weapons made in Pakistan
on behalf of Saudi Arabia are now sitting ready for delivery.
